I think it makes best sense if there is a single mode that:
 - Uses and requires MIT kerberos
 - Only builds non AD DC components (starting by omitting the AD DC
binaries and provision tools, possibly also some libraries)

That way we satisfy all these needs with one combination.

Later, if there is development to have an MIT KDC work for Samba4 (not a
small task, but you have done well with these so far), then we can
revisit this.
